TRUSS Filed Jan. 16 1933 BENJAMIN F PEASE INVENTOR sy' rf it ATTORNEY.10 ed studs Patented Apr. 24, 1934 STATS UNE'F restate N'i GFFICE FAT11 6 Claims.

This invention relates to trusses, particularly to spring frame trussesand to improvements in back pads therefor.

In spring frame trusses of ordinary construc- 5. tion, the rear ends ofthe frame terminate in spaced relation at the back of the truss. A backpad is positioned on each end and a connecting strap is employed to holdthe truss in an operative position. The frame is provided with headwhichproject outwardly from the rear face of each pad and the same areconnected by a strap having apertures in which said studs are entered.As the heads of the studs project outwardly beyond the strap, theclothing of the wearer is brought into forced contact therewith and issoon worn away or torn.

Objects of the invention are to provide a truss of simple durableconstruction, which will overcome this objection; which will be highlyeffi- V cient in use and may be comfortably worn without injuring theclothing.

A further object is to provide a truss having back pads at each end ofthe truss frame with the outer face of the adjacent ends of the padoffset inwardly to provide a seat for a connecting member whereby themember and the fastening means will be positioned in a plane spacedforwardly from the rear face of the pads and which will present arelatively smooth even surface having no objectionable protruding partswhich will tend to tear or wear away the clothing.

The above objects are accomplished and additional ends are attained bythe novel construction, combination and arrangement of parts hereinafterdescribed and illustrated in the accompanying rawing, it beingunderstood that the invention is not confined to the particular formsiown or restricted to the particular type of truss illustrated and thatthe structure may be 4Q subjected to variations which come within thespirit of the invention as set forth in the appended claims.

In the drawing:

Figure 1 is a perspective view of a truss constructed in accordance withthis invention,

F ure 2 a cross sectional view taken as indicated by the lines 2-2 ofFigure 1,

Figure 3 is a perspective view of the improved base plate employed incarrying out the invention and showing the end portion of a spring sidemember attached thereto.

While the invention is adapted for application to trusses of differenttypes, in the drawing there is illustrated a truss having a continuousspring frame 5 adapted to encircle the body of the wearer with the freeends of the frame 5 terminating in spaced relation at the back of thetruss. Each of the free ends of the frame 5 is provided with a pad 6which is adapted to bear against the back or hip portion of the wearersbody. Each pad 5 comprises a base plate '7; a cushion 8 and a pad facing9 of leather or other suitable material. The base plate 7 is providedwith a threaded bore 10 and each of the ends of the frame 5 arepositioned flat against the rear face of one of the plates '7 and issecured thereto by means of a screw bolt 11 which is positioned throughan aperture in the frame memher and threaded in the bore 10.

The forwardly presented face of each free end portion of the frame 5 isthus positioned in the same plane with the rear face of the plate 7 towhich it is secured. Each plate 7 is provided at the free end thereofwith an extension 12 which is ofiset inwardly from the plane of the mainportion of the plate 7. The offset shoulder 13 is preferably arcuate inform, thus adding materially to the strength and durability of the baseplate and providing means for supporting the cushion element 8 and forproviding an extension 12 which will possess great rigidity even whenthe plate '7 is composed of relatively thin material.

The extension 12 on one of the plates 7 is provided with a threaded bore14 and the extension 12 on the other plate '7 is provided with a glovefastener stud 15 which projects rearwardly from the rear face thereofand is welded, riveted or otherwise secured thereto. The rear face ofeach of the pads 6 is covered with a layer 16 of leather or othersimilar material which is secured to the facing 9 by the stitching 17.

In the particular adaptation of the invention shown in the drawing, thelayers 8 and 16 are extended forwardly to provide a cover for the framemember 5.

The numeral 18 denotes a connecting strap having one end thereof securedto the extension 12 on one of the plates '7 by means of the screw 19which is threaded in the bore 14. In the particular form of trussillustrated, the layer 16.

It will thus be seen that this invention provides a truss provided withback pads 6 having the rear face of the adjacent ends thereof offsetforwardly to provide a seat for the ends of the fastening element 18awhereby the free ends of the frame 5 may be detachably connected andwhich has no objectionable protruding studs to wear away or tear theclothing of the wearer.

It will be seen that the layers 9 and 16 completely cover the extension12 of the base plate 7 forming a pad extension 6a. The inner face of thepad extension 6a is disposed in a plane positioned outwardly from themain bearing face of the pad thereby providing an extension 6a whichwill not contact with the body of the wearer.

Having thus illustrated my invention and described the same in detail,what I claim as new and desire to secure by Letters Patent is:-

1. In a truss, a frame for embracing the body of the wearer, said frameterminating in spaced relation at the back of the truss, a back pad oneach end of said frame, said back pads having the adjacent ends thereofoffset inwardly to provide a seat for a connecting element, a connectingelement and means to detachably secure the connecting element to theoffset portions of said pad.

2. In a truss, a frame for embracing the body of the wearer, said frameterminating in spaced relation at the back of the truss, a back pad oneach end of said frame, said back pads having the adjacent ends thereofoffset inwardly to provide a seat for a connecting element, a connectingelement and means to detachably secure one end. portion of saidconnecting element to the offset portions of one of said pads and snapfastener means for detachably securing the other end of the connectingelement to the offset portion of the other pad.

3. In a truss of the character described, a frame, for encircling thebody of the wearer, said frame having two end portions terminating inspaced relation at the back of the truss, a back pad on each endportion, an extension on the free end of each pad, each extension havingan outer face disposed in a plane spaced inwardly from the outer face ofthe pad, a strap for connecting said pads and means on said extensionfor detachably securing the ends of the strap thereto.

4. In a truss of the character described, a spring frame for embracingthe body, the free ends of said frame terminating in spaced relation atthe back of the truss, a back pad on each end of said frame, each backpad comprising a base plate, means securing said base plate to theframe; an extension on the free end of said base plate, said extensionbeing offset forwardly in relation to said base plate, a cushion elementon the inner surface of the main body of the plate, a flexible sheath onsaid pad, said sheath enclosing said cushion and extension and meansassociated with said extension and projecting rearwardly therefrom forsecuring a connecting element thereto.

5. In a truss of the character described, a back pad, said back padprovided on the rear face thereof with a surface offset inwardly fromthe main surface of the rear face of the pad and means to detachablysecure a connecting element fiat against the offset portion of said pad.
